This method should create a new widget with the provided parent.
This will only be called if the form did not already provide a widget, so it is not guaranteed to be called! You should not do initialization stuff, which also has to be done for custom editor widgets inside this method. Things like filling comboboxes and assigning other data which will also be used to make widgets on forms created in the QtDesigner usable should be assigned in initWidget().
parent | You should set this parent on the created widget. |

This method should initialize the editor widget with runtime data.
Fill your comboboxes here.
editor | The widget which will represent this attribute editor in a form. |

overrideprotectedvirtual |
Returns true
if the widget has been properly initialized.
This acts as hint for the calling party if this wrapper can be used after initializing it. If it cannot be used this is a hint to the caller that he may try to find another suitable widget type instead.
